Abstract

|
|
|
The lateral meniscus is morphologically more variable than the medial meniscus. An abnormal lateral meniscus also varies with respect to its size, shape and stability, and such variations can occur in any patient of any age. The most common variant is a discoid lateral meniscus. We recently encountered a patient with a discoid lateral meniscus for which the anterior horn of the meniscus was anomalously inserted into the anterior ACL. The patient was forty five years old women who had persistent pain for three to four years without any specific trauma history. She was preoperatively diagnosed as having discoid lateral meniscus by MRI, and was confirmed the presence of the complex tear and anomalous insertion of the anterior horn of the discoid lateral meniscus into the anterior ACL by arthroscopic examination. Arthroscopic subtotal meniscectomy was performed and the symptoms were improved after surgery.
